Problem Upgrade 4.30 to 4.50.1

I am working to upgrade nop 4.30 to 4.50.1, exists previus DB. When I compile the debug generated an error in CookieAuthenticationService.cs on line 108
var authenticateResult = await _httpContextAccessor.HttpContext.AuthenticateAsync(NopAuthenticationDefaults.AuthenticationScheme);
[System.NullReferenceException: 'Object reference not set to an instance of an object.']

The HttpContext return null value.

Anyone with an idea how to solve it? Has this happened before?

I appreciate the help

Are you using 3rd party plugins?
If you still have problems, post the entire stack trace here.

Hi New York, Thank you very much, the link in the post helped me a lot. Yes, I am using third party plugins, but I already managed to solve the HttpContext problem with the old link from the forum post. Now after compiling I get this error:

This page isn’t working right nowlocalhost redirected you too many times.
To fix this issue, try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

Normally I edit the Store table and in the Url field I change from https to http and in the SSLEnable field I put False and that usually works, but not this time. Do you have any idea to solve that?

Try an incognito/private browser (or try another browser - e.g. Edge rather than Chrome).  If it works there, then you need to clear your cookies and do a hard refresh.
